This invention relates to, and has for a main object to produce, an improved' stock quotation projecting machine in which the motor is continuously operating and the tape pulling device becomes inoperative when the ticker stops.

It is still another object/of the present invention to provide an improved stock quotation projecting machine in which the control for the pulling sheave is all contained in the sheave itself,

thereby reducing the space ordinarily required for such control to a minimum and as in this case completely saving such space.

It is still another object of the present invention to produce an improved slip clutch device for the tape pulling sheave of a stock quotation projecting machine in which the sheave is mounted freely to rotate on the driven shaft, a stationary clutching element is fixed to said shaft, a movable clutching element is connected to the 2 sheave and means are provided for normally and yieldably causing said clutching elements to clutchingly engage one another. f

It is still another object of the present invention to provide an improved stock quotation pro- ,jecting machine in which a slip clutch control pulling sheave will cooperate with a tape vibration dissipating device to facilitate said device in following up the slack in the tape to iron out the vibrations transmitted thereto and to deflnitely anchor the pulling sheave against rotation .when the ticker is at, rest so as to relieve the tape of any undue strain during ythis period of rest.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specic embodiments thereof illustrated in the accompanying drawings in which Figure 1 is a l side elevation of a machine equipped according'to one embodiment of the invention;

Fig. 2 isan end elevation enlarged of the tape pulling mechanism:

Fig. 3 is a transverse section substantially on the line 3 3 of Fig. 4 still further enlarged showing the clutch in detail;

Fig. 4 is an enlarged section on the line 4-4 of Fig. 3 showing the clutch in gripping engagement; Fig. 5 is a section similar to the section of Fig. 4 showing the clutch out of gripping engage Fig. I is an enlarged fragmental side elevation of a part of the tape control mechanism; and

Fig.- 8 is an enlarged fragmental end elevation of the tape control mechanism of this embodiment. 5 In the embodiment illustrated in Figs. 1 to 5 inclusive, there is showna stock quotation projecting machine having a ticker of the high speed type illustrated as enclosed in the casing I from which the tape Tpasses under the finger 2 to the 1o roller 3 at the entrance end to the light aperture' formed on the extension 4 of the lamp housing 5 from which the tape T passes over the roller 6 and then down around the tape pulling roller on sheave 'I mounted to freely rotate on the l5 shaft 8 of the reduction gearing contained in l the housing 9 from which the tape T passes to the rewind reel I0.

The shaft 8 has fixed thereon and disposed in the housing 9 a worm wheel II in mesh with the worm I2 mounted on the shaft I3 extending at right angles to the shaft 8 and journaled in the housing 9 below the shaft-8. The shaft I3 is provided with a pulley I4 connected to the pulley l5 of the motor ls by the belt l1. 25

The shaft 8 has formed on the outside of the housing 9 a pulley I8 connected to the pulley I8 by the spring belt 20, the pulley I9 being mounted on the shaft 2| journaled inthe bearing 22 at the upper end of the arm 23, the rewind reel 30 I0 being secured to said shaft 2l, as illustrated in Fig. 2.

The finger 2 in the present embodiment is formed at the end of an extended arm or lever 24 pivotally connected to the bracket 25 extend- 35 ing upwardly from the extension 4. Such arm 24 preferably has a weight 26 adjustably mounted thereon to facilitate controlling the tension on the.tape T by the nger 2.

Extending upwardly from the housing 5 is 40 formed the bracket 21 at the upper end of which is mounted the housing 28 for the objective lens which receives the images formed of the characters on the tape and directs them upwardly to the mirror 29 which in turn deflects them o'nto the 45 mirror 30 which in turn deiiects them onto the screen 3l.

The main part of the present invention consists essentially of the clutching mechanism for the tape puller or sheave 'I and its cooperation 50 with the vnger 2. This clutching mechanism consists essentially of a lined clutching element 32 and a movable clutching element 33. The xed clutching elementl see particularly Figs. 3, 4, and

5 consists of a drum 34 having a hub 35 xedto 55 Y the shaft 8 by the pin 88. The movable clutching element consists of an arcuate finger pivotally connected to the disc 81 also mounted to rotate freely on the shaft 8.

-This movable clutching element has an inwardly extending projection Il having an arcuate innerface disposed` to engage the periphery of the drum 84.when in clutching engagement therewith. This clutching face of the projection 88 is normally and yleldably maintained Ain engagementl with the periphery of the drum 84 by the spring 89 extending from the in 48 near the free end of the finger 88 to the pln44| extending laterally froin the disc 81. The extreme end of the linger .88, to wit the portion 42 is adapted to engage the pin 42 extending inwardly from the inner periphery of the cylindrical wall 44 of the sheave 1.

From the foregoing, it will be seen thatthe clutch control or clutching mechanism will have different angular movements relative to the drive shaft andthe tape puller 1. see particularly Fig. 4, when the tape T is being discharged by the ticker and free' to be drawn in the ldirection of the arrow 45, the spring 89 will be free to thrust the pin 48 and therewith the sheave 1 out of its way to permit its projection 88 clampingly to engage the drum 84 and travel with the drum 94 which is driven by the shaft 8 in one angular relation in the direction offthe arrow 45 in Fig. 4

' or the arrow 46 in Fig. 3.

Onlthe other-hand, if the ticker stops, the reaction of the tape T will be in the direction of the arrow 41 in Fig. 5 whereupon the pin 48 will engage the end 42 of the finger 88 to oppose the action of the spring 99 in turn to cause the friction face of the projection 88 to permit the drum 34 to slip relative to said projection 88 in another angular relation. J

'I'he sheave 1 as illustrated in Fig. 3 is preferably 'composed of two parts as illustrated, one having the disc portion 48 integral with the cylindrical wall 44 and having an annular ange 49 at its edge, and the other having a disc portion 58 with a shouldered recess 5| formed to frictionally receive the end of the cylindrical wall 44 and provided with a ange 52, the tape T engaging the outer periphery of the wall 44 and being guided in position'on the sheave 1 by the flanges 52 and 49.

For causing the sheave 1 to drivlngly engage the tape T, the roller 58 is provided, it being journaled in the bracket 54 pivoted at 55 and provided with the arm 56 on which is adjustably mounted the weight 51, the roller 58 frictionally pressing the tape T into engagement with the sheave 1.

In the embodiment illustrated in Figs. 6, 'l and 8, the tape pulling sheave is practically identical with the tape pulling sheave 1 of the embodiment illustrated in Fig. 1 arranged however in this instance to permit the tape to move over the upper face thereof and equipped to cooperate with the vibration dissipating lever.

The tape Tf in this instance passes from the ticker, preferably of the high speed type contained in the housing 58 to the light aperture disposed on the extension 59 of the lamp housing 68 and then passes over the tape pulling sheave 6| in engagement with which the tape is maintained by the idler 62. From the tape pulling sheave 6|, the tape passes down under the idler 68 mounted on the side of the housing 64 and then passes over to the rewind reel 65 mounted on the shaft 66 journaled in the end ofthe bracket 61 extending from the housing 64.

At the entrance and discharge ends of the light aperture, there are formed the rollers 68 and 69 as indicated to facilitate the movement of the tape across such light aperture. Between the ticker and the roller 68, the finger 18 of the lever 1l engages the upper face of the tape T'. The lever 1I then extends across the extension 59 to the link 12 to which it is pivotally connected and which in turn is pivotally connected at 13 to the upper end of the housing 64, the lever 1| and link 12 thus, forming and serving as a split lever. The link 12 is provided with a small recess 14 to receive the pin 15 extending from the side of the housing 64, the cooperation of the pin 15 with the ends of the slot 14 determining the limit of movement of the link 12. For yieldably maintaining theflink 12in raised position with the lower end of its slot 14 in engagement with the pin 15, there is 'provided the spring 16.

Thev lever 1| is provided with a short arm 11 having a downwardly extending finger 18 pro-` vided with a flaring face 19. 'Ihe finger 18-is adapted to engage the teeth 88, four in number in the present instance, extending from the disc 8|, constituting a rotative element, which forms a guiding ange for the tape T on the sheave 6I. The sheave 6| is similar to the sheave 1 of theA embodiment illustrated in Fig. 1, and has a cylindrical housing 82 which in the present instance extends from the disc 8l and has secured thereto the disc 83 to form the other 'guiding flange for the tape T passing over such sheave 6|.

'I'he discs 8| and 83 of the sheave 6| are mountedon the shaft 84 which in the present instance is the driven shaft journaled in the housing 64 having xed thereon the worm wheel 85 in mesh with the worm 86 fixed on the shaft 81 vjournaled in the housing 64. On the outwardly `extending end of the shaft 81, there is fixed the pulley 88 which is connected to be driven by the pulley 89 by the belt 98. 'I'he pulley 89 is xed on the shaft 9| of the motor 92.

On the shaft 84, there is also secured the pulley 98 which is connected to drive the pulley 94 on the shaft 66 of the reel 65 by means of the spring belt 95.

'Ihe pressure roller 62 for maintaining the tape T in driving engagement with the sheave 6| is preferably journaled inl the end of the bracket 96 having the extension 91 and pivotally connected to the housing 64 by the pin 98. For maintaining the roller 62 in such driving engagement, the spring 99 is provided connecting the extension 91 with the abutment |88 extending from the housing 64. 'I'he sheave 6| is drivingly connected to the shaft 84 by the clutching device illustrated in detail of Fig. 3 of the first described embodiment. It has a drum |8| extending from the shaft 84 and fixed to rotate therewith. Freely rotatable on the shaft 84 inside of the sheave 6|, there is mounted the disc |82 which has plvotally connected thereto the arcuate lever |88 which has a clutching projection |84 formed thereon which is resiliently maintained in engagement with the periphery of the drum I8I by the spring |85. When the tape T' is being discharged by the ticker and it is free to be taken up by the pulling sheave 6|, the spring |85 will rst move the sheave in the direction of rotation by the cooperation of the pin |86 extending from the cylindrical portion 82 with the lever |88 whereupon the clutching face |84 of the lever |03 will engage the drum IUI to cause the sheave 6I to -turn with the shaft I4.

From the foregoing, it will also be seen that if when the ticker comes to rest and no further tape is being discharged 'from it for the moment, the pulling sheave 6| will continue to draw the tapeA across the light aperture and thereby take up the slack under the finger 10, in turn to cause the finger 18 to be depressed into the path of act the jar that might otherwise be transmitted to the tape by the v'sudden engagement of the finger 18 with the tooth 80and thus cause a slight retardation in the drawing action of the tape before finally coming to rest.

This flexible action between the finger 1 8 and tooth 80 will also cooperate with the friction clutch contained in the sheave 6I to produce a smooth and even start and stop of the tape and to insure the formation of a loop suciently large under the nger 'l0 so that the stopping of the pulling sheave will overlap at least two and possibly three printing impulses so that in turn the starting and stopping of the pulling sheave will not correspond tothe insignificant starting and stopping of the tape with each printing impulse and that as a result thereof the sheave will only come to rest when the ticker has come to rest after the transmission of a message or a series of characters where the interruptions or arrest of the tape exceeds the time interval required to print at least two characters and preferably three characters.

It is obvious that various changes and modications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
